Unobtanium C8 Z06 HF Cat Pipe Stainless

High flow sport cats for the C8 Z06

The factory catalytic converters on the C8 Z06 are built around emissions and packaging first, which leaves some flow and weight on the table. The Unobtanium C8 Z06 HF Cat Pipe Stainless replaces the stock cat section with a high flow, motorsport style assembly designed to support serious power levels while keeping exhaust gas control in place for appropriate use.

Each set uses a 5" GESI GEN2 Advanced G-Sport UHO+ core that is rated for applications up to roughly 1000 horsepower, combined with precision CNC machined flanges and carefully built tubing for consistent fit and durability. The assemblies are TIG welded and then finished with Cerakote coating and DEI Titanium wrap to help manage radiant heat and maintain near stock like heat containment in the engine bay and tunnel.

Built to live in a harsh environment

These high flow cat pipes are designed specifically for the C8 Z06 and the conditions the LT6 sees on track and back roads. Proper flange design and quality welds help the system seal and stay stable under heat and vibration, while the high quality G-Sport cores are intended for modern, high output engines. In practice, you get a reduction in backpressure compared to the factory pieces and a sharper, more responsive feel as the engine moves through the rev range, especially when paired with Unobtanium headers and cat back components.

As with any change to catalytic converters or exhaust flow, overall results and sound will depend on the rest of the system, calibration and how the car is used. If you are planning a full package around your C8 Z06, we can help you decide how these HF cat pipes fit with headers, cat back and tuning so you end up with something that matches your goals.

Important: Modifying or replacing catalytic converters can affect emissions compliance and noise regulations. These parts are intended for off road or competition use where allowed. Always confirm and follow the laws in your region.
